The supervolcano that lies beneath Yellowstone National Park in the US is far larger than was previously thought, scientists report.
A study shows that the magma chamber is about 2.5 times bigger than earlier estimates suggested.
A team found the cavern stretches for more than 90km (55 miles) and contains 200-600 cubic km of molten rock.
The findings are being presented at the American Geophysical Union Fall Meeting in San Francisco.
Prof Bob Smith, from the University of Utah, said: Weve been working there for a long time, and weve always thought it would be bigger... but this finding is astounding."
If the Yellowstone supervolcano were to blow today, the consequences would be catastrophic.
The last major eruption, which occurred 640,000 years ago, sent ash across the whole of North America, affecting the planets climate.
Now researchers believe they have a better idea of what lies beneath the ground.
The team used a network of seismometers that were situated around the park to map the magma chamber.
Dr Jamie Farrell, from the University of Utah, explained: We record earthquakes in and around Yellowstone, and we measure the seismic waves as they travel through the ground.
The waves travel slower through hot and partially molten material with this, we can measure whats beneath.
This is more of a real threat than the AGW voodoo that so many believe in.

Spoken like a true Flat Earther. Referring to a worldwide scientific consensus on the reality and dangers of AGW as "voodoo" just further demonstrates how extremely demented you are, Klod.
I'd love to visit one last time before she blows. That place is awesome.

In the world of tiny brained morons that you obviously inhabit, Don'tKnowShit, what exactly is the supposed significance of Antarctica being very cold relative to the observed, many decades long warming trend the rest of the planet has been experiencing?
Or to the fact that 2013 will be the seventh warmest year on record globally, or to the fact that Austalia, another Southern Hemisphere continent, is currently experiencing its hottest year on record?

Citing fraudulent, thoroughly debunked articles, written by a denier cult stooge for a right wing British tabloid, as evidence for your demented fantasy that the Earth is cooling, actually only demonstrates how extremely gullible and ignorant you are, Don'tKnowShit.

If she blows it won't matter. It's unlikely you'll survive.
